4 Claims.

This invention relates to a vacuum and pressure filling apparatus for fluid, plastic or various other materials and the method of filling containers therewith.

The essential object of the invention is the production of apparatus, by means of which a partial vacuum is produced in containers and by means of which a measured quantity of material is forced into the containers.

The second object of the invention is the production of apparatus, by means of which the productivity of filling containers with a material is greatly increased.

The third object of the invention is the production of iilling apparatus for containers, by means of which the material charged into the containers is not hindered by the resistance of the air displaced from the containers. n p

The fourth object of the invention is the production of apparatus, by means of which viscous materials can be introduced into containers and at the same time obliterate air pockets in the containers.

The fth object of the invention is the production of apparatus, by means of which containers of varying inside diameters can all be filled to a uniform height.

The sixth ob-ject of the invention is production of apparatus for filling containers, which can be easily applied to the various types of pressure filling machines now in use, such as piston displacement machines, compressed air operating machines, gravity lling machines and the like.

The seventh object of the invention is the production of apparatus, by means of which containers can be easily filled with charges of material, and which avoids splashing said material over the mouths of the containers when filling the same.

In the accompanying drawing, Fig. l represents an elevation partly in vertical section of an exemplication of the apparatus for lling containers, by a piston displacement system coacting with a vacuum; Fig. 2 indicates an enlarged fragmentary of Fig. l, Fig. 3 is a section of Fig. 2 on the line 3, 3 and Fig. 4 shows a section on the line 4, 4 of Fig. 1.

A valve casing is indicated at having theV ports 2l, 22 and 23. The upper end of the casing 28 has integral therewith the flange 21. At one side of the casing 20 is shown the internally threaded sleeve 28 and at the lower end of said casing is indicated the internally threaded sleeve 29. A valve 30 having the connecting ports 3| and 32 at right angles to each other is rotatively sup- Cil ported in the casing. An arm 30a extends from the valve 30.

A supply hopper 35 is indicated with its supporting flange 36 having the port 31. The flange 36 and the latter is recessed for the disc 36a is supported upon and fastened to the ange 21, by means of bolts as shown, and the port 31 is in alignment with the port 2 l; A measuring cylinder 42 has kone end thereof in threaded engagement with the sleeve 28 and is axially in line with the port 22. A reciprocating piston 45 is provided for the cylinder 42. A connecting rod 46 is shown with the ends 46m and. 46h; The A'end 46a is pinned to the piston 45. An operating arm 41 is indicated with the longitudinal slot 48. A block '49 is positioned in the slot 48; The block 49 is shown with the threaded shank 56 with a nut as shown. A collar 5I is integral withthe block 49 and from said collar 5l extends the journal hub 52 with the detachable collar 53. The end 461) of the connecting rod is supported on the journal hub 52. By varying the position of' the block 49 in the slot 48 the operator can vary the stroke of the said piston 45. p

A vacuum hood is indicated in its entirety by the numeral 55. The said hood is shown with the axial chamber 56 which has the flared lower end 51 and connects with the inlet opening 58. A vacuum tube 59 having the'opening 60 in its upper portion is detachably positioned in the chamber 56 of the vacuum head 5 5. A detachable filling tube 6I in the vacuum head 55, extends from the opening 58 to below the lower end of the vacuum tube 59. A flexible seat 63 coaxial with the tube 6I is tightly positioned in place at the upper portion of the flared lower end 51 of the vacuum hood 55.

A threaded boss 65 at the upper end of the hood 55 is in threaded engagement with the sleeve 29. A port 66 having the tapered threaded portion 61 is shown in the upper portion of the hood 55. In the port 66 is positioned the sleeve 68,7which is coaxial with the opening 60 and bears against the vacuum tube 59. 4

A platform 10 i`s positioned below the vacuum hood 55 and is indicated with the opening 1|. A reciprocating table 14 extends through the opening 1l and is provided for supporting the containers, in the exemplication the bottles 15.

A vacuum reservoir with the outlet valve 8| for an outlet opening is positioned below the platform 10. A vacuum pump 82 is shown with its inlet piping 83 and the latter leads from the reservoir 80. Vacuum piping 85 with the member 86 leads into the reservoir 80 and has connected therewith a shut oil? valve 88, which is automatically operated by the lever 89. l

In the member 86 is indicated the release valve 92, which is automatically operated by the lever 93. To the member 86 is attached the manifold 98 and from the later may extend a plurality of nipples 99 to be connected to a plurality of vacuum heads 55 and their appurtenances. In this instance only one of the nipples 99 and oneof the heads 55 are indicated in operating position, and

caps are provided for the nipples not in use( In this instance one of the said nipples 99 is shown with the coupling |03 and from the latter extends the tapered plug ||J5 which is in threadedengagement with the threaded tapered portion 61 of the port 66. Y

To operate the vacuum and pressure filling apparatus, the material handled is charged into the supply hopper 35. Ihe vacuum pump 82 is started and by means of which a vacuumis produced in the vacuum reservoir 80. The bottles are positioned upon the reciprocating table 14, which seats the upper ends `of said bottles against the flexible seat 63 to make them vacuum tight. At the same time the piston 45` is reciprocated, by means of the operating arm 41 and its appurtenances. When the piston 45 moves in the direction of the arrow A, a measured quantity of the material handled is drawn from the supply hopper 35, through the ports31, 2|, 3|, 32 and 22, when the valve 30 ispositioned as indicated in Fig. 1. At the same time the table 14 rises and locates the bottle 15 with its `upper end in tight contact with the exible seat 63. Slightly before locating the bottle 15 in place, the valve 88 is automatically opened and the valve 92 ismaintained closed. By this means a partial vacuum is produced in the bottle 15. The valve 30 is now automatically turned by the arm 30a to connect theport 3| withthe cylinder 42 and the port 32 with the port 23. The piston is now moved in `a direction' opposite to the arrow A, and ejects the measured'quantity of kmaterial therein into the bottle 15 through the lling tube 6|; Thevalve 88 is then 'automatically closed to cut off fthe vacuum from thebottlel, and the valve 92 is opened to release the vacuum in the hood 55. Next the bottle 15 is lowered with the descent of the table 14.

In case the bottles 15 vary in their internal diameters, so that the upper levels of the charges of the material therein vary, the aparent surplus of the material above the lower end of the vacuum tube 59 will be drawn from the bottles in the annular space between the vacuum tube59 and the filling tube 6| and will enter the vacuum reservoir 68.v The material in the reservoircan be removed therefrom by opening the outlet valve 8|.

Instead of the reciprocating table 14 to position the bottles 15 in place, the apparatus may be constructed to reciprocate the. vacuum hood 55 and its appurtenances, to properlyV contact the upper ends of the bottles 1,5 with said hood.
